ÖzBu çalışmada, sonlu elemanlar yöntemi kullanılarak analizler yapılmış ve otomotiv endüstrisinde kullanılan altı farklı malzemenin şekillendirilebilirlikleri incelenmiştir. Belirli bir geometride ve başlangıçta 1,5 mm kalınlığında olan malzemeler için sanal ortamda derin çekme işlemi uygulanarak malzemelerin şekillendirme sınır diyagramları elde edilmiştir. Her bir malzeme için ayrı ayrı elde edilen diyagramlar üzerinden şekillendirilebilirlikler karşılaştırılmış ve deformasyon zorlukları değerlendirilmiştir. Analiz sonuçları doğrultusunda Niyobyum, Titanyum ve Vanadyum elementlerinin malzemelerin şekillendirilebilirliğini negatif yönde etkilediği, Alüminyum elementinin ise şekillendirmeye olumlu etkisi olduğu tespit edilmiştir. AbstractIn this study, analyses were made using the finite element method and the formability were examined of six different materials used in the automotive industry. Deep drawing simulation was made of materials with a specific geometry and initial thickness of 1.5 mm and forming limit diagrams were obtained. The formabilities were compared over the diagrams plotted separately for each material and the deformation difficulties were evaluated. According to the analysis results, it was determined Niobium, Titanium and Vanadium elements had negative effects and Aluminum element had a positive effect on formability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
